Since I have the extra Baldor motor for the mill I am going to see what happens if I run the motor at 120hz that will make the 1725rpm motor run at 3450rpm and the spindle run about 5000rpm. Don't worry I will make a video and post it.......

My landlord couldn't understand the concept of a cnc milling machine so I made this to put on his desk.... Hopefully some other people will see it and I'll get some calls for side work....

2x9x1" milled 1/2" deep 6061 aluminimum

It looks like garbage up close but it does have that 10 foot quality..... I figured out a few problems during this run, this was the last piece of stock this size so I'm not running it again for free.......lol

How about flipping it and doing the back side too with less DOC? I can't tell you how many times I've engraved on my Tormach on both sides.

I have one of the strangest problems with the cnc bridgeport..... When milling aluminum and running coolant, the old coolant and oil that's dried on the machine gets wet then drips down to the work piece..... I'm guessing the old dried oil contains lots of sulfur because it turns the aluminum brown or black..... It must be time to clean the head off.....

Just made a test cut of a side project I'm doing...... 2 gears cut in the face..... I had a bad tool path broke a 1/16" end mill.... I'll try again but I need to adjust my tool paths a little ....

I'm looking at a fairly old part milled trying to figure out what went wrong.... Can some of you CNC guys give me some ideas......

O1 soft TGP .750" OD, koolmist with noga mister
Solid Carbide 4 flute 5/32, 2700rpm 2D pocket

I'm kinda guessing that its half of it was backlash, I can adjust that..... But I also think my tool path could be part of it maybe wasn't fast enough

1st pic is spindle side work orgin.... wall thickness .020" lol

2nd pic is vise side.... wall thickness .040"

Depth of cut not enough per move?

I love all of your ideas. Thank You.
